Do you want to use R for it? If yes you can read the file and set -9999 as missing value see ?read.table further on you can change not NA values to 1 by your.data[!is.na(your.data)] <- 1 and NA values to 0 by your.data[is.na(your.data)] <- 0 Regards Petr > > What should I do, > > Thanks > Taiseer > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
